PDA Programming

[Santiago Bravo]

Hi All,

I created an application for a company (programmed in Java of course ) which maintains customer details in a database. I have now been asked by the company to get the same app on the PDAs that the managers use.

Im totally new to this and need some help on the following questions if possible:


1. Can I program the same app in Java ME?
2. What are the advantages and disadvantages of using Java ME?
3. Are there any other good alternatives to Java ME?
4. Can Java ME be used on any PDA which has the JRE?

Basically im trying to find out if programming applications on a PDA is similar to programming for PC applications.

Any tutorial links would also be very helpful


Thanks all

It depends on which classes you have used. See my answer to 2.

2. What are the advantages and disadvantages of using Java ME?

You are missing a lot of classes, and the I/O model works quite differently.

It most definitely is not, unfortunately. Besides the disadvantages I named, you need to learn complete new classes for the user interface alone. There is no such thing as Swing or AWT in ME.


Oh, and your definitely selling yourself short here, putting this thread in the beginner's forum. Even if it wouldn't fit in the ME forum, it would fit a lot better in the intermediate forum than here.

You're right Rob, but maybe ME would be a better forum.

Thanks for moving the forum.

The app that I created interacts with a database and there are some I/O functionaliy.

Would this just be a case of learning J2ME to program for a PDA?

Is J2ME just as robust, scalable etc as J2EE?


Thanks
